As a small step towards making it easier to quantify our reports, I've written a program that attempts to measure tremor. It is available online at:

There is nothing to install; it should run directly from the web page.

The program requires that you have a pointing device that picks up your tremor. If this does not happen, the results are meaningless.

I've been using a laptop's touchpad. Sometimes I get good results, sometimes bad. This is where I need your help. Can you find a way to increase sensitivity while, at the same time, not affecting the tremor's behaviour? For instance, I've tried putting washers and springs between the pad and the finger.

I realize that tremor is a complicated issue, not least that it varies with time, and that this program only gives a snapshot value. But I believe that some measurement is better than none. I also hope this effort will spur on other people to do better. It would be great if sometime soon all PwP had free tools to measure their symptoms.
